Try the documentation Math blocks

and http://www.appinventor.org/bookChapters/chapter18.pdf

perhaps something like this if ! is not a factorial symbol

depending on what you mean by

(1/3%)^5! for example 1/3 percent or 33 percent or whatever.

The Math Blocks does not have a factorial or percentage operator.
